I understand why you would say that. I frequently think the same thing and have been banned from plenty of communities for suggesting much less. But, let's stop for a second and examine some options that don't involve prison or getting yourself killed.
It is possible to lower the number of nazis without ever violating a single law. The advantage of clever strategies are multi-fold. The biggest advantage is you become very difficult to stop if you operate within the bounds of the law. Operating illegally is temporary (you are likely to be caught or worse). It also accomplishes very limited results. An active shooter might take out a dozen targets but a CEO can legally affect the lives of millions. We need to be thinking on commercial scales if we want real results.
We don't want overt violence unless we are in an active war or troubles scenario. It's just not as effective or safe as legal, more subtle methods.
I recommend editing or deleting your comment. Not because I completely disagree with the sentiment, but because the mods have a duty to protect these communities from the forces that are looking for an excuse to shut them down. We'd rather have your participation than lose you to a ban. Check my post history and mod log to see how little it can take to get banned.
